Question

ПАЛОЧКА ЭТО ДРОБЬ 2/11*9/25+8/11*9/25 И ВТОРОЕ 24(3/8-1/12)

Answer 1

2/11*9/25 + 8/11 * 9/25 = 9/25 (2/11+8/11) = 9/25 * 10/11 = сокращаешь 18/55
24 (38/ - 1/12) = 24/1 * 3/8 - 24/1 * 1/12 = сокращаешь первую дробь и вторую = 3/1*3/1 - 2/1*1/1= 9-2=7

Answer 2

2/11 * 9/25 + 8/11 * 9/25 = 18/275 + 72/275 = (18+72)/275 = 90/275 = 18/55
24(3/8 - 1/12) = 24 * 3/8 - 24 * 1/12 = 24/1 * 3/8 - 24/1 * 1/12 = 9 - 2 = 7
